(Cl. 1262) Thisinvention relates to a camp stove. More particularly, the inventionrelates to a camp stove utilizing cans of fuels such as jelled alcoholtype fuel.

The invention may be described as a camp stove for utilizing jelledalcohol fuel. More particularly, but not by way of limitation, theinvention may be described as a camp stove for utilizing cans of jelledalcohol fuel comprising an open top, flat bottomed, shallow containerbase, an opened top, flat bottomed fuel can container member of adiameter less than said container base and centrally positioned withinsaid container base, said fuel can container member of a diameter toreceive a said can of jelled alcohol fuel, a hard setting ballast in thelower portion of said container base surrounding and holding in positionsaid fuel can container, a base cover member closing said containerbase, said base cover member having an opening therein receiving theupper portion of said fuel can container, said base cover member havinggrilled support openings therein, a fuel can container member coverremovably closing said fuel can container member, said fuel cancontainer member cover having an opening therein, and a removable grillmember extending across the said opened top of said fuel can containermember, said grill member having integral downwardly extending portionsremovably received by said grill support openings in said base covermember.

A principal object of the invention is to provide an improved camp stoveutilizing jelled alcohol fuel.

More particularly, an object of this invention is to provide a campstove for utilizing jelled alcohol fuel providing a device havingimproved heat dissipation means so that the stove itself is heated to aminimum extent by the combuston of the fuel.

Another object of this invention is to provide a camp stove forutilizing jelled alcohol fuel including a simple, inexpensive but sturdydevice having improved ballast means to prevent the possibility of ittipping over while in use.

Another object of this invention is to provide a camp stove forutilizing jelled alcohol fuel including a flame control lid memberwhereby the heat produced by the stove may be controlled and furtherproviding means whereby the stove may be extinguished.

Another object of this invention is to provide a camp stove whichutilizes jelled alcohol fuel having two identical units supported toeach other in a manner such as to provide an easily handled integral twoburner unit.

These and other objects and a better understanding of the invention maybe had by referring to the following description and claims, taken inconjunction with the attached drawings in which:

3,152,585 Patented Oct. 13, 1964 Referring now to the drawings and firstto FIGURE 1, a single stove unit is indicated generally by the numeral10. Stove unit 10 consists basically of an opened top, flat bottomedshallow container base 12, a base cover member 14 closing the upperopening of the base member 12, a fuel can container member cover 16, apivotally supported flame control lid made up of portions 20A and 25B, agrill 22 and a handle 24. The internal construction and the functioningof the elements of the device will be described in detail subsequently.

FIGURE 2 discloses an embodiment of the invention utilizing two of thestove units 10 which are joined together by a brace member 26 affixed tothe base member 12 of each stove unit at the lower portions thereof anda handle member 28 extending between the stove units 10 and connected ateach end thereof to the base 12. The handle member 28 is positionedabove the brace member 26 in such a way that by grasping the handlemember 28 the stove units 10 balance each other and, as will bedescribed subsequently, ballasts in the lower portions of base members12 of each of the stove units 10 make the complete integral unit ofFIGURE 2 easily portable. The dual unit of FIGURE 2 is more or less anoptimum embodiment since most occasions for utilizing a camp stoverequire more than one flame for purposes such as preparing coffee on oneof the units while preparing food on the other.

FIGURE 2 shows the grill 22 and the fuel can container member cover 16removed showing means whereby a can 30 of jelled alcohol fuel may beinserted into the stove unit or the can removed when it is completelyburned.

Referring to FIGURE 3, the stove unit is shown in somewhat betterdetail. Affixed to pivot about pin 32 is the flame control lid 20A.Flame control lid 20A is a flat cover having an integrally formedextending handle portion 20B by which the lid is moved. The lid is showncompletely covering opening 34 in the fuel can container member cover16. In this closed position a flame, if one had previously existed, isextinguished. By dotted outline the lid 20A is shown in a fully openposition providing complete exposure of opening 34 allowing maximumflame. Intermediate positions between these two extremes permit variousamounts of opening 34 to be exposed to produce varying quantities offlame and therefore varying heat amounts. When the cover member 20A ispositioned to cover approximately one-half of the total area of opening34, then the heat produced by the flame is approximately one-half of thefull opening heat.

Referring now to FIGURE 4, a cross-sectional view, the internalarrangement of the device is best shown. An opened top, flat bottomedfuel can container member 36 is centrally supported within the basemember 12 and is held in proper position by a quantity of solidifiedhard setting ballast material 38, concrete, plaster of Paris, orpreferably a commercial product known as Hydrostone, are examples ofmaterials which may be used for ballast 38. In FIGURE 4 a small quantityof the ballast ma terial 38 is shown between the exterior bottom of fuelcan container member 36 and the interior bottom of base member 12, at38A. This layer of ballast material 38A serves to insulate against heattransfer to the bottom of the stove unit but, the tendency of the stoveto heat at the bottom being not of serious consequence, the preferredarrangement is to position the fuel can container member 36 in directcontact with the interior bottom of base member 12 so that all of theballast material 38 is in the annulus surrounding container member 36.

In the preferred embodiment as shown, the lower portion 40 of the fuelcan container member 36 is tapered inwardly so that a can 30 of jelledalcohol fuel, when positioned within the stove, is centered, leaving anannulus air space 42 between the can 30 and the interior of the fuel cancontainer member 36. This air space provides insulation to prevent thestove itself from becoming heated as the fuel within can 30 burns.

Aflixed to the downwardly extending side of the fuel can containermember cover 16 and extending horizontally is a narrow lid support 44which receives a rivet 32 by which handle portion 20B is pivotallysupported.

As can be seen in FIGURES 3 and 4, the integrally formed handle portion203 of the flame control lid 20A terminates in an upturned portion 46A.The upturned portion is exceedingly handy to remove the lids fromcontainers such as those usually utilized to close jelled fuel cans.When it is desired to open a can of jelled alcohol fuel, the upturnedportion 46A of handle 29B is inserted under the lip of the can lid. Witha downward motion the lid is pried off. In like manner the end of thelid support 44 is downwardly turned at 46B. The downwardly turnedportion 463 may equally be used to pry off can lids. The divergence ofportions 46A and 46B facilitates pivoting of the flame control lid.

Grill 22 has integrally formed downwardly extending portions 48 whichenter openings 50 in the base cover member 14 by which the grill 22 isremovably supported on top of the cooking unit. As shown in FIGURE 5,clips 52 are spot welded to the inner surface of base cover member 14 tolimit the extension of the downwardly extending portions 48 within holes50 so that the grill 22 is supported at a proper height about thecooking unit.

The stove unit of this invention has been described as a camp stoveunit, although it is apparent that it has many other applications, suchas the use in storm or fallout shelters and for emergency cooking orfirst aid units and so forth. T he camp stove unit of this device isformulated by round containers but it is obvious that containers ofvarious other configurations may be utilized to make up the componentsof the invention.

The camp stove unit of this invention provides a simple, inexpensive,yet very durable cooking unit formulated in such a way, with ballast 38,so that the device is very difficult to overturn.

The stove is constructed in such a Way that good insulation is providedpreventing the stove itself from heating during use.

This invention has been described with a certain degree ofparticularity, but it is manifested that many changes may be made in thedetails of construction and arrangement of components without departingfrom the spirit and scope of this disclosure.
